d) Decrease a number by 32% is the same as multiplying by 68%

If you want to know what's the value of x in 2 functions, you need to do a single variable equations.

Answer:

-30

Step-by-step explanation:

The product of M x N is {4a + 8b + 12c}.

Given are the matrices as -

M = {a, b, c} and N = {4, 8, 12}

We can write the product as -

M x N = {4a + 8b + 12c}

Therefore, the product of M x N is {4a + 8b + 12c}.

Answer:

5 root 2 for both

Step-by-step explanation:

y=x= 10/root two

= 5 root 2

if my answer helps please mark as brainliest.

Answer:

x = 5*sqrt(2)

y = 5*sqrt(2)

Step-by-step explanation:

Because the triangle is a 45-45-90 triangle, 10 is equal to x * sqrt(2) and x = y.

x = 10 / sqrt(2)

When simplified:

10 / sqrt(2) = (10 * sqrt(2))  / 2 = 5 * sqrt(2)

Answer:

(0,3)

Answer:

-8w=16

Step-by-step explanation:

-5w-9+9 = 3w+7+9

-5w=3w+16

-5w-3w=3w-3w+16

-8w=16

To solve:

-8w/-8=16/-8

w = -2

Answer:

5×4+9

Step-by-step explanation:

The product of something means to multiply, so you would multiply 5 and 4 together.

Then you would add 9 to that.

Answer:

value of QZ = 8 units and QM =  12 units.

Step-by-step explanation:

Given: In triangle PQR has medians QM and PN that intersect at Z.

If ZM = 4 units.

In the figure given below;  second median divided the two triangles formed by the first median in the ratio 2:1.

We have to find the value of QZ and QM;

QZ:ZM = 2: 1

⇒

Substitute the value of ZM =4 units and solve for QZ;

Multiply both sides by 4 we get;

Now, calculate QM;

QM = QZ+ZM = 8 + 4 = 12 units.

Therefore, the value of QZ and QM are; 8 units and 12 units

Answer:

B

Step-by-step explanation:

It's B

3^5 = 243

so the 5th root of 243 is 3

(x^7)^(1/5) = x^(7/5)

(y^10)^(1/5) = 7 ^(10/5) = 7^2

z^(21)^(1/5) = z^(21/5)

Answer:

Step-by-step explanation:

volume of 154×100×84 box = 1,293,600 cm³

dimensions of airspace = (154-4) by (100-4) by (84-4) = 150 by 96 by 80

volume of airspace = 150×96×80 = 1,152,000 cm³

volume of wood used = 1,293,600 - 1,152,000 = 141,600 cm³

Answer:

$6.75

Step-by-step explanation:

To find the unit price, just divide the total price ($47.25) by the quantity (7).

Step-by-step explanation:

Answer:Researchers say a psychiatric condition characterized by a person's mistaken belief that he or she smells bad is vastly under-recognized. Called olfactory reference syndrome, the condition is "probably very common," says Katharine Phillips, MD, of Rhode Island Hospital in Providence. so you might just be thinking thst in your head man. just shower, brush teeth etc... or this could be a possibility...What causes the unpleasant smell is the bacteria that build up on your sweaty skin and react with sweat and oils to grow and multiply when sweat reacts with bacteria on the skin. These bacteria break down proteins and fatty acids, causing body odor in the process.

Answer:

x=3

Step-by-step explanation:

Answer:

y-2x=8 (label equation 1)

16+4x=2y (label equation 2)

divide equation 2 by 2 to find y

y=2x+8

sub this in equation 1

(2x+8)-2x=8

2x+8-2x=8

8=8

once you get to this point because 8=8 there are an infinite number of solutions because you can't divide by 0. So the answer is B

[tex] \frac{5}{y} = \frac{5 + 3 }{y + x} [/tex]

[tex]5(y + x) = y( 5 + 3)[/tex]

[tex]5y + 5x = 8y[/tex]

[tex]5x = 8y - 5y[/tex]

[tex]5x = 3y[/tex]

[tex] \frac{x}{y} = \frac{3}{5} [/tex]

[tex]x = 3[/tex]

[tex]y = 5[/tex]

Answer:

y=3 and x=0

Step-by-step explanation:

3x−3y=−9. i'm going to solve for x.

3x−3y+3y=−9+3y

3x=3y−9

3x/3=(3y-9)/3  to isolate x we have to divide everything by 3

x=y−3

so now that we have x we can substitute it in 4x+4y=12

4(y-3)+4y=12

4y-12+4y=12

8y-12=12

8y-12+12=12+12

8y=24

8y/8=24/8

y=3

we have y which equals 3, so now we can substitute it into any equation so solve for x again.

3x – 3y = -9

3x-3(3)=-9

3x-9=-9

3x-9+9=-9+9

3x=0

3x/3=0/3

x=0

so, final answers are y=3 and x=0

checking our work:

3(0)-3(3)=-9

0-9=-9

-9=-9 true

4(0)+4(3)=12

0+12=12

12=12 true
